Growing directions
Plant in extremely well-drained, lean, alkaline to neutral, sandy or gravelly soil in full sun; Spanish lavender (L. stoechas) is the most heat- and humidity-tolerant of the lavenders, making it the best choice for Gulf Coast zone 8–9 gardens where English lavender (L. angustifolia) typically fails from summer humidity. It produces distinctive flowers topped with long, rabbit-ear-like purple bracts in spring, with a repeat bloom in fall. Like all lavenders it requires perfect drainage — root rot in wet or heavy soil is the most common cause of death. Plant in a raised bed or on a slope in amended sandy soil. Harvest stems when flowers are half-open; dry hanging upside down for wreaths and sachets. Shear by one-third after each bloom flush to maintain compact growth.
